Hauv thaj teb ntawm cov kav hlau carbon, ASTM A500 Qib C thiabASTM A106 Qib Cyog ob qho qauv khoom siv uas feem ntau siv. Txawm hais tias ob qho tib si yog cov hlau carbon thiab sib koom ua "Qib C", lawv txawv ntawm kev tsim qauv, cov txheej txheem tsim khoom, thiab cov xwm txheej siv. Tsab xov xwm no muab kev sib piv ntxaws ntxaws los ntawm ntau qhov ntev, suav nrog cov lus txhais tus qauv, cov tshuaj lom neeg sib xyaw, cov khoom siv kho tshuab, cov lus qhia txog qhov ntev, thiab cov chaw ib puag ncig siv tau.
1. Cov Lus Txhais Txheem thiab Cov Ntawv Thov Tseem Ceeb
ASTM A500 - lub npe tag nrhoCov Qauv Txheem rau Cov Yeeb Nkab Carbon Steel Uas Tau Tsim Los Ntawm Txias Thiab Tsis Muaj Qhov Txuas Hauv Cov Puag Ncig Thiab Cov DuabRaws li lub npe qhia, qhov no yog tus qauv raj qauv, siv tau rau cov raj carbon steel uas tau vuam txias thiab tsis muaj qhov sib txuas. Nws feem ntau yog siv rau hauv kev tsim cov thav duab, choj, thiab lwm yam qauv rau kev sib txuas welded, riveted, lossis bolted. ASTM A500 npog qib A, B, C, thiab D, nrog Qib C yog qib siab tshaj plaws uas siv feem ntau.
ASTM A106 - lub npe tag nrhoCov Qauv Txheem rau Cov Yeeb Nkab Hlau Carbon Seamless rau Kev Pabcuam Kub SiabQhov no yog tus qauv yeeb nkab kub siab, tsuas yog siv rau cov yeeb nkab carbon steel seamless, tsim tshwj xeeb rau kev xa cov pa dej, kua dej, thiab lwm yam xov xwm hauv qab qhov kub thiab txias thiab siab. ASTM A106 npog qib A, B, thiab C, nrog Qib C yog qib muaj zog tshaj plaws.
Qhov txawv ntawm ib kab lus tseem ceeb: A500 Qib C yog lub raj xa dej uas muaj lub nra hnyav; A106 Qib C yog lub raj xa dej siab rau kev thauj kua.
2. Cov Txheej Txheem Tsim Khoom thiab Cov Ntawv Khoom
Ob tus qauv no txawv ntau heev hauv txoj kev tsim khoom thiab cov duab muaj:
| Aspect | ASTM A500 Qib C | ASTM A106 Qib C |
|---|---|---|
| Kev Tsim Khoom | Txias-ua welded (ERW) los yog seamless | Tsuas yog tsis muaj qhov sib txuas (kub-ua tiav los yog txias-kos) |
| Cov duab | Puag ncig, plaub fab, plaub fab plaub fab, thiab cov seem tshwj xeeb | Tsuas yog puag ncig xwb |
| Txoj kev txiav txim | Los ntawm sab nraud txoj kab uas hla × phab ntsa tuab (OD × WT) | Los ntawm qhov loj me ntawm cov yeeb nkab (NPS) thiab tus lej teem sijhawm |
Lub peev xwm ntawm A500 los npog cov seem plaub fab, plaub fab plaub fab, thiab lwm yam uas tsis yog voj voog yog qhov kev cuam tshuam ncaj qha ntawm nws qhov dav - "hauv Cov Puag Ncig thiab Cov Duab" - uas A106 tsis muaj.
3. Qhov ntau thiab tsawg
ASTM A500 Qib C: Siv tau rau cov raj uas muaj qhov ntev tsis tshaj 2235 hli (88 nti) thiab phab ntsa tuab tsis tshaj 25.4 hli (1 nti). Cov raj plaub fab feem ntau tuaj yeem ncav cuag 22 nti × 22 nti. Kev kam rau siab ntawm phab ntsa: qhov tsawg kawg nkaus ntsuas phab ntsa tuab yuav tsum tsis pub tsawg dua 90% ntawm qhov tuab phab ntsa teev tseg.
ASTM A106 Qib C: Siv tau rau cov kav dej tsis muaj qhov sib txuas nrog cov kav dej loj NPS ⅛ txog NPS 48 (DN 6 txog DN 1200), nrog rau phab ntsa tuab raws li ASME B36.10M (cov sijhawm 10 txog 160, XXH, thiab lwm yam). Kev kam rau phab ntsa tuab: qhov ntsuas phab ntsa tsawg kawg nkaus yuav tsum tsis pub tsawg dua 87.5% ntawm qhov ntsuas phab ntsa tuab.
4. Kev Sib Piv Txog Cov Tshuaj Lom Zem
Qhov sib txawv ntawm cov tshuaj lom neeg sib xyaw ua ke qhia txog qhov yuav tsum tau ua haujlwm sib txawv. A106 Qib C xav tau silicon (Si ≥ 0.10%) los txhim kho kev tiv thaiv cua sov thiab kev tiv thaiv oxidation, thaum A500 Qib C tsis muaj kev xav tau silicon. A106 kuj tseem txwv tsis pub muaj cov khoom tsis zoo xws li phosphorus thiab sulfur kom ntseeg tau tias muaj kev ntseeg siab hauv qab qhov kub thiab siab.
| Khoom (siab tshaj plaws,%) | ASTM A500 Qib C | ASTM A106 Qib C |
|---|---|---|
| Cov pa roj carbon (C) | 0.27 (kev tshuaj xyuas khoom) | 0.35 |
| Manganese (Mn) | 1.40 (kev tshuaj xyuas khoom) | 0.29 – 1.06 |
| Phosphorus (P) | 0.045 (kev tshuaj xyuas khoom) | 0.035 |
| Sulfur (S) | 0.045 (kev tshuaj xyuas khoom) | 0.035 |
| Silicon (Si) | Tsis tas yuav tsum muaj | ≥ 0.10 |
Qhov tseem ceeb, cov ntsiab lus carbon ntawm A500 Qib C (0.27%) qis dua li ntawm A106 Qib C (0.35%), uas muab A500 Qib C zoo dua weldability thiab txo qhov kev pheej hmoo ntawm kev tawg thaum lub sijhawm vuam.
5. Kev Sib Piv Txog Cov Khoom Siv Kho Tshuab
Lub zog ntawm lub hom phiaj sib txawv: A500 Qib C muaj lub zog tso zis siab dua, ua rau nws zoo dua rau kev tiv thaiv kev hloov pauv mus tas li hauv cov khoom siv, thaum A106 Qib C muaj lub zog tensile siab dua, qhia txog nws lub peev xwm los tiv taus lub siab sab hauv thiab tiv thaiv kev tawg.
| Vaj tse | ASTM A500 Qib C | ASTM A106 Qib C |
|---|---|---|
| Lub Zog Tsawg Kawg Nkaus | 345 MPa (50,000 psi) | 275 MPa (40,000 psi) |
| Lub Zog Tensile Yam Tsawg Kawg Nkaus | 425 MPa (62,000 psi) | 485 MPa (70,000 psi) |
| Qhov Ntev Tsawg Kawg Nkaus | 21% | Feem ntau siab dua, tsim rau kev khoov, flanging, thiab lwm yam. |
A106 Qib C muaj kev ywj pheej zoo dua, ua rau nws tsim nyog rau kev khoov, flanging, thiab lwm yam kev ua yeeb nkab. A500 Qib C, ntawm qhov tod tes, ua tiav nws lub zog siab los ntawm kev ua haujlwm hardening thaum lub sijhawm txias.
6. Cov Chaw Ib Puag Ncig thiab Cov Cai Engineering Siv Tau
Ob tus qauv no siv rau hauv cov chaw sib txawv thiab ua raws li cov qauv tsim sib txawv:
| Aspect | ASTM A500 Qib C | ASTM A106 Qib C |
|---|---|---|
| Qhov kub thiab txias | Cov qauv ruaj khov ib puag ncig thiab qhov kub qis; tsis muaj qhov yuav tsum tau ua haujlwm kub siab | Tsim tshwj xeeb rau kev pabcuam kub siab, txog li ntawm 427 ° C thiab siab dua |
| Cov ntawv thov ib txwm muaj | Cov thav duab tsev, cov choj trusses, cov tshuab txhawb nqa, cov qauv pej thuam | Cov chaw ua roj av, cov chaw tsim hluav taws xob, boiler kub siab / siab siab pa dej thiab cov kav dej ua haujlwm |
| Cov lej tsim qauv | AISC (American Institute of Steel Construction) cov qauv kev cai | ASME B31.1 (Cov Kav Dej Fais Fab), B31.3 (Cov Kav Dej Txheej Txheem), thiab lwm cov lej kav dej siab |
7. Cov Lus Qhia Txog Kev Xaiv
Hauv kev xaiv cov khoom siv engineering, cov ntsiab cai hauv qab no tuaj yeem siv tau:
- Ua ntej duab: Yog tias daim duab hu rau cov raj plaub fab, plaub fab, lossis cov raj tshwj xeeb, xaiv ASTM A500 Qib C - A106 tsis tsim cov duab no hlo li.
- Rau cov raj puag ncig, xav txog kev siv: Yog tias nws yog ib qho kem qauv, kab pheeb ces kaum, lossis cov khoom siv truss uas raug cua, cov khoom tuag, lossis lwm yam zog sab nraud → xaiv ASTM A500 Qib C. Yog tias nws yog cov khoom siv txuas cov yeeb nkab, xa cov pa lossis cov kua hydrocarbon hauv qab siab thiab kub → xaiv ASTM A106 Qib C.
- Kub: Rau cov khoom siv hauv qhov kub thiab txias, xaiv A500 Qib C; rau cov kav dej uas yuav ua haujlwm tas li ntawm qhov kub siab (≥350 ° C), xaiv A106 Qib C.
Hauv luv luv: rau kev thauj khoom ntawm cov qauv, siv A500 Qib C; rau kev thauj cov kua dej kub siab, siv A106 Qib C. Ob qho no tsis tuaj yeem hloov pauv tau hauv kev tsim kho.
